Ever wondered what separates a gem dealer who's confident in every sale from one who's constantly second-guessing? Usually, it's not experience alone it's the equipment on their bench.

In India's gem trade, accuracy isn't optional. A misread on a diamond tester, an uncalibrated scale, or a cheap polishing wheel can quietly cost a business far more than the tool itself was worth. So let's talk about what actually belongs in a serious gemologist's or jeweller's toolkit.

The Essentials

🔹 Diamond & Synthetic Screeners — With lab-grown diamonds flooding the market, a reliable tester that can flag CVD/HPHT stones isn't a luxury anymore, it's basic due diligence.

🔹 Gold & Platinum Testers — Devices like Auracle testers check purity (6K–24K) without damaging the piece — a must for exchange counters.

🔹 Faceting & Cutting Machines — Precision angles = brilliance. This is where raw rough becomes a finished gem.

🔹 Gemological Microscopes — Inclusions, treatments, and origin clues hide in plain sight — if your magnification is weak, so is your grading.

🔹 Calibrated Weighing Scales — Because "close enough" isn't a pricing strategy.

Why Supplier History Matters

Anyone can sell a box of tools online. Far fewer suppliers have actually grown up inside the trade. That's the difference worth paying attention to a supplier who understands why a gemologist needs a specific lighting setup, not just that they ordered one.

Case in point: Johari Tools, operating out of Jaipur's Johari Bazaar since 2001. What started as a gemstone tool marketing company evolved into a full-scale supplier for India's jewellery industry testers, microscopes, faceting machines, scales, packaging carrying trusted names like Presidium, Nikon, Ohaus, and GemOro. Today they serve customers not just across India but in the US, Europe, and Australia too, with special pricing available for gemological labs and students.

Bottom Line

Your tools are only as good as the trust behind them. Before you buy your next tester, scale, or microscope, look past the price tag check the supplier's roots in the trade.
